OVEN.

The Schedule referred to in 'these Letters Patent and making part of the same.

To all whom it may concern:

Figure II isa partial sectional view, out vertically through the oven.

The object of my improvements is to obtain economy of fuel, evcnness of temperature, and convenience of operation.

These points I obtain, the construction is as follows:

The heating-space of the'oven is confined between two cylinders, an inner one, A, and an outer one, B.

There are two chimneys, G and D, the one, C, in front, and the one, D, in rear, both in a direct line with the fire-box.

The heat travels around the cylinder A on each side, near its base, through dues E, which are of equal size and length on each side, and are perforated with holes, F, so that the heat can-pass out into the bakingspace Gr, between the two cylinders.

The middle of this space is occupied -by a rotating baking-pali, H, which is formed in segments, and put together in the. shape of a ring, around the inner oven wall A.

This ring rests upon friction-wheels I, and is guided by means of a rim, J, underneath, the rim J enclosing'v and guiding against the outer ii'iction-wheels.

rIhe baking-pan is revolved by means of a pinion, K, meshing with a circular rack, L, underneath the baking-pan, outside ofthe rim J.

The friction-wheel shafts, as well as the pinion shaft, have their bearings in the outer and inner walls; and the pinion-shaft is turned by power from the outside of the oven-walls.

The oven-door X is usually situated above the firebox, and opens directly before the baking-pan. v

A bonnet, M, is placed at this point, so that the current of air either from 'the oven or into it is interrupted asmuch as possible, and the 'ba-ker thereby prevented from being burned, andthe oven from being unduly cooled when the oven-door is opened.'

This bonnet m'ay be set at any height to allow different thicknesses of bread to pass under its sides.

The method of arranging the dampcrs and chimneys allows the heat of the oven to be regulated toa nicety. A,llach chimney, C and D, is provided with a damper. A

A pipe, N, communicates between the baking-space G and the chimney D, entering the latter just above the dampler.

Now, when the dampers in both chimneys are open,

the. draught is such that the iire kindles easily, heat ing the oven 'but little, but when both damper-s are shut, the heat is forced out through the holes F in the dues E into the space G, iinding it way into the chimney D, through the pipe N. Should the baker then desire to moderate the heat of the oven, he can open the damper in thc chimney C, and thus produce a direct draught from the fire.

`By this means, I accomplish my purposes in a simple and convenient manner, realizingA economy, couvenience of operation, and perfect results at little cost beyond that of ordinary! masonry.

Now, having described my invention,

Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The construction of the oven herein shown, in which the baking-space G is contained between the inner and outer walls A and B, in which the revolving baking-pan H is also arranged in the manner substan tially as set forth.

2. rlhe combination of the walls A and B, chimneys O and D, fines E, and pipe N, the chimneys being arranged with dampeis, and the parts being all constructed and arranged substantially as described.

3. In combination with the oven herein shown, the circular rotating baking-pan H; working upon frictionwheels, and operated by rack and pinion, substantially as shown.

4. In combination with the baking-pan H, the bonnet M, arranged as and for the purpose set forth.
